JEROME N. ADAMS, OF NEUHABDT, ARKANSAS.

ROPE AND CABLE CLAMP.

messes.

Application filed December 29, 1914.

To all 1.0 ham it may concern Be it known that I, JEROME N. ADAMS, a citizen of the United States, residing at Neuhardt, in the county of Crittenden and State of Arkansas, have invented certain new and useful Improvements in Rope'and Gable Clamps, of which the following is a specification.

This inventionrelates to rope and cable clamps and has particular reference to means for locking the same in a desired position.

The object of my invention is to provide a rope clamp of the above character in which a fine range of adjustment is attained, so as to facilitate the application of my invention to ropes and cables of various sizes.

Another object of my invention is to provide a device in which the above objects are attained through a simple construction, a device which is cheap to manufacture and one which is durable.

With the above and other objects in view my invention resides preferably in the construction, combination and arrangement of parts set forth in the following specification and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved clamp; Fig. 2 is a vertical sectional view through the same; Fig. 3 is a vertical sectional view on the line 33 of Fig. 2; and Fig. i is a transverse sectional view on the line ell of Fig. 2 and looking in the direction of the arrows.

Similar reference characters indicate similar parts throughout the various views of the drawings.

Referring more particularly to the drawings in which the preferred embodiment of my invention is illustrated, I provide a body portion 1 which serves as a casing or frame, the said body portion 1 having a plurality of recesses 2 therein, said recesses 2 being disposed substantially in parallel relation and adapted to receive for slidable movement the shanks or arms 3 of a shackle 1 forming a clamping element. The arms 3 are preferably of a size which will insure their snug movement within the recesses 2 so as to prevent wabbling or lost motion. As is shown to advantage in Fig. 2 the said shackle 4 is preferably U-shaped in contour, being formed of a single bar of metal or the like, bent upon itself as shown. The inner face of the shackle 1 adjacent Specification of Letters Patent.

Serial No. 879,580.

the point at which the same is bent is provided with a. pluralityof serrations 5 for a purpose which will be hereinafter set forth. a

I The upper face 6 of the body portion 1 13 provided with a substantially arcuate recess 7 disposed preferably between the arms 3 of the shackle l. 'The surface of the sald arcuate recess 7 is provided with a plurality of serrations 8.

It will be seen from the above description that when an object such as a rope or cable, is inserted between the areuate face 7 and the shackle t forced downwardly, the said object will be gripped between the serrated face 7 and the shackle e, the serrations 5 and 8 of the shackle and face 7, respectively, engaging the object and retaining the same therein.

I have provided an improved means for locking the shackle l in clamped position. The opposing faces 9 of the arms 3 are provided with a plurality of teeth 10. The said body portion 1 is provided with recesses 11, the said recesses 11 extending inwardly from the longitudinal center of the body as shown to advantage in Fig. 2, and extend lateral to and communicate with the recesses 2 hereinbefore described. Disposed within the recesses 11 are a plurality of members for locking the shackled in clamped position, which preferably comprise pawls 12 and 13, the pawls 1:2 being of a length slightly greater than the length of the pawls 13, as shown to advantage in Figs. 2 and 3. The said pawls 12 and 13 are mounted upon transverse shafts l ll, said shaftsll being mounted in the walls of the recesses 11, and the pawls 172 and 13 rotatably mounted thereon and disposed in a position substantially parallel to the arms 3 of the shackle l. The said pawls 12 and 13 are similar in construction, having their lower ends cut away as shown at 15 to provide shoulders for engagement with the teeth 10 on the arms 3 of the shackle 4:. It will be seen that this provides handles or finger engaging portions 16 for facilitating disengagement of the pawls 12 and 13 with the arms 3 of the shackle 4.

In order to insure engagement of the pawls 12 and 13 with the teeth 10 on the arms 3 spring elements 17 are provided carried by the body portion 1 as shown at 18, having their free ends in spring pressed engagement with the pawls 12 and 13. It will there are two sets of pawls l2 and 13, it

I being noted that when the pawls 12 are in engagement with the teeth on the arms 3 that the pawls 13 will be disengaged there from by virtue oftheir lesser length and also their contact with the inclined face of the adjacent tooth, but it will be seen that when the shackle a is forced farther down into clamping engagement with an object, the pawls 13 will then engage the next succeeding tooth, and it will thus be seen that a very fine range of adjustment is provided.

From the above description taken in connection with the accompanying drawings it is thought that a clear and comprehensive understanding of the construction, and advantages of my invention may be readily had by those skilled in the art, and it will be seen that I have provided a clamp which is simple in construction and one which affords a device which will positively engage and hold an object desired to be clamped, and at the same time provides a fine range of adjustment, and also is provided with a means for locking the same which may be readily unlocked at the will of the user.

While I have shown and described my invention as possessing a peculiar form and portion having a plurality of perforations therein, a shackle slidably mounted in said perforations, said body portion having. a plurality of laterally disposed recesses communicating with the said perforations, teeth on said shackle, and pawl locking members mounted in said lateral recesses and engageable with the teeth on said shackle, said pawls being of different sizes, and successively engaging the said teeth, as and for the purpose set forth.

3. A rope and cable clamp, including a body having a plurality of perforations therein, a shackle slidably mounted in the perforations, said body having laterally extending recesses communicating with the perforations, and locking spring pressed pawls in the recesses engageable with the arms of the shackle, said pawls extending beyond the body to facilitate manual releasing of the shackle.

4-. A rope and cable clamp, including a body having parallel perforations therein, a shackle having toothed arms slidable in said perforations, said body havinga plurality of recesses communicating with the parallel perforations, pawls pivoted in said recesses JEROME N. ADAMS. Vitnesses:
